• Program Terminates On File Move

  - by Merus

  I have a .Net program that, as one of its functions, takes a file from a user-specified directory and puts it in another, special, directory, specified via UNC (which may or may not be local). I don't open any of these files in this part of the code. There's this bizarre bug I'm having where, on a Windows Server 2003 SP2 VM, this program randomly does a hard abort while doing the move to a local folder. It just terminates. No exception, no logging, and it doesn't appear to happen at any particular moment. I can't reproduce this problem on my development machine, and it only appears to happen during the copy of a particular kind of file that's about a megabyte or so. There are other formats copied to different directories using very similar code, all smaller, and they work fine. Why would a Windows .Net program do a hard abort like this? What can I do to fix it?

• Calling C++ function from C.

  - by claws

  I know this. Calling C function from C++: If my application was in C++ and I had to call functions from a library written in C. Then I would have used //main.cpp extern "C" void C_library_function(int x, int y);//prototype C_library_function(2,4);// directly using it. This wouldn't mangle the name C_library_function and linker would find the same name in its input *.lib files and problem is solved. Calling C++ function from C??? But here I'm extending a large application which is written in C and I need to use a library which is written in C++. Name mangling of C++ is causing trouble here. Well I cannot use C++ compiler over my C project because thats breaking lot of other stuff. What is the way out? By the way I'm using MSVC

• My company is a Rackspace Cloud client (provided to us for free) and I'm trying to find some way to set up version control

  - by Nick S.

  As the title says, my (small) business is provided a free Rackspace Cloud client account. We receive a decent amount of traffic but I haven't been able to put together a business case to move to our own server yet. However, we are developing some complex apps and I'm frustrated with not having the ability to even ssh into the remote server. Ultimately, I'd like to set up some sort of version control (at this point, I'll take anything, git or otherwise). I have control over databases, can FTP, set up cron jobs, and perform a few other basic functions. I can't think of any way to set up git or something similar without ssh access. A thought went through my mind that maybe some sort of PHP version control exists that I might be able to set up, but I haven't had any luck finding it yet. Do you guys have any ideas, thoughts, or advice?

• Are there any alternative to the header(); function ?

  - by Simon

  The thing is, I have a log-in page. And, when user enters Username & Password, they must be re-directed to success/failure page. Now, I have placed a "header('location:welcome.php');" after mysql rows are returned. But, it is giving me Header already sent errors, and I don't know much about PHP to do anything about it, let alone understand why it is happening. So, how to you transfer a user to another page after log-in data is verified? Same problem is happening with register, post, comment and search functions in my site.

• jQuery .html() vs .text() produce different result in .hover() function

  - by Paddy

  I have a issue where in I am using the .hover() function. If I use .text() fuction to add the html (anchor tag) which I am dynamically creating, it works fine, both the functions are called as desired. But when I use the .html() function instead then the second fuction of .hover() is never been called. var i = 0; textItems = new Array(); ////I am putting the value into textItems using the jquery ajax call ////and i get its value from a .each() function. //.text() implementation $('#textArea-id').hover( function() { $('#textArea-id').text(textItems[i]); }, function() { //-->mouseout function is called here } ); //.html() implementation $('#textArea-id').hover( function() { $('#textArea-id').html(textItems[i]); }, function() { //-->mouseout function is never been called } );

• Undefined reference to "func" when compiled with GCC

  - by hotlemontea

  I implement a link list in two files in linklist.h and linklist.c, and I call some functions defined in linklist.h in main function of main.c. linklist.h is included in both linklist.c and main.c. When I compile this program by GCC with Makefile, the error named "undefined reference to xxx" occurs. I think my Makefile is written correctly as below. So what is the possible reason for this linking error CC=gcc CFLAGS= -g -O2 TARGET=target OBJECTS=main.o linklist.o TARGET: $(OBJECTS) $(CC) $(CFLAGS) $(OBJECTS) -o $(TARGET) clean: rm target $(OBJECTS) main.o:linklist.h linklist.o:linklist.h

• Input Iterator for a shared_ptr

  - by Baz

  I have an iterator which contains the following functions: ... T &operator*() { return *_i; } std::shared_ptr<T> operator->() { return _i; } private: std::shared_ptr<T> _i; ... How do I get a shared pointer to the internally stored _i? std::shared_ptr<Type> item = ??? Should I do: MyInterfaceIterator<Type> i; std::shared_ptr<Type> item = i.operator->(); Or should I rewrite operator*()?

Any pointers will be appreciated. Many thanks.

• wordpress: previous_post_link() / next_post_link() placeholder

  - by superUntitled

  I am having trouble with the previous_post_link() and next_post_link() functionality. When there is no previous post, the function previous_post_link() does not display a link, likewise for the next_post_link() and the last post. I would like to have a placeholder image so that the design stays consistent. Currently I have images of green arrows pointing left and right, I would like to place an image of a grey arrow if there are no more posts to go back to. Is there a way to use the next_post_link()/previous_post_link() functions but not have the link removed. I also wonder if there is a way for the links to cycle, so that if you come to the most recent post, the next post link would bring you back to the first post.

• Can jquery capture the dynamic dom events and perform actions

  - by Zombie15

  I just wanted to know if something like this is possible. Jquery should fire some action on certian custom event. Like Whenever a new row is added to dom dynamically to table then i have certain action like change the background color to example red. That should work across the whole site. Somethings like Event listeners in Doctrine2 or Signals in Django EDIT: Basically i want some thing like where i can create custom event $.AddnewEvent(newRowAdded); Then i can customise that event with my own functions like $.newRowAdded(function(){ blah blah });

• C++ Boost bind value type {solved}

  - by aaa

  hello. I look in documentation and source code but cannot figure out how to get return value type of boost bind functor. I am trying to accomplish following: 35 template<typename T,size_t N, class F> 36 boost::array<typename F::value_type, N> make_array(T (&input)[N], F unary) { 37 boost::array<typename F::value_type, N> array; 38 std::transform(input, input + N, array.begin(), unary); 39 return array; 40 } where F can be bind functor. the above does not work because functor does not have value_type. for that matter, is there standard interface for unary/binary functor as far as return value. solution: it should be result_type. also equivalent defined are argument_type and first/second_argument_type for binary functions Thanks

• Path Inclusion/Global variable not working?

  - by Dan LaManna

  Simply put, my config file includes my database class, and the config file has in it: global $db; $db = new database(DB_HOST, DB_NAME, DB_USER, DB_PASS); That file is root/config.php Moving on to root/functions/func.newpage.php doesn't have any includes/requires, and uses $db-classfunction since the file I'm working with: root/newpage.php - requires the config file, as well as func.newpage.php. However I still come up with: Undefined variable db. Anything you guys are seeing I'm not? Thanks! Let me know if more details are needed.

• How to Handle Console.log and error output in JavaScript.

  - by uber_n00b

  I have a constructor that has a series of classes and functions within it - in each function I check if the param is set to show the error and output if so. Like so using an inline if. The issue and question is short of keeping two versions is this approach not wise in that each IF has to be evaluated thus adding to the time it takes to perform? debugSlide = (bag.debug==1)? console.log("item id =" + bag.itemId) : 0; How do you do this? Any pointers on where I can find tips on this? Thanks in advance!

• C# Get/Set Syntax Usage

  - by RoR

  These are declarations for a Person class. protected int ID { get; set; } protected string Title { get; set; } protected string Description { get; set; } protected TimeSpan jobLength { get; set; } How do I go about using the get/set? In main, I instantiate a Person Tom = new Person(); How does Tom.set/get?? I am use to doing C++ style where you just write out the int getAge() and void setAge() functions. But in C# there are shortcuts handling get and set?

• Boost singleton trouble

  - by Ockonal

  Hi guys, I have some class which uses boost singleton. It calls some function from own c++ library. This library is written in make file as dependence. Now I have another singleton class and it should call first singleton class. After this code I got linkers error about undefined references for functions which are used in first singleton. When I remove calling first singleton class from second the errors remove. Maybe there is something wrong?

• including a string as a parameter to a function in a header file? c++

  - by Nara

  hello everyone, total newbie is here :) i have this header file, zeeheader.h, and i wrote some classes in it, i'm having problems giving a string as a parameter to one of the functions: class DeliTest { public: void DeliCheck(Stack*,string); void ComCheck (unsigned,string); bool EofCheck (unsigned,string); }; as i was implementinng it in the cpp file, i added #include to it, it seemed to be working, for example : as i was writing the "data." i got the "length()" appear by the intellisense, so i thought that it was working, but it wasn't. i got errors like: syntax error : identifier 'string' overloaded member function not found in 'DeliTest' this is one of the fucntions in the cpp file: bool DeliTest::EofCheck(unsigned i, string data) { if (i == data.length()-1) return 1; return 0; } am i supposed to be adding something to the header file??

• How can I login linux using C or C++

  - by jnblue

  I need to programmely switch the current user to another,then the followed code should be executed in the environment(such as path,authority..) of another user. I've find the 'chroot()','setuid()' may be associated with my case, but these functions need the root authority, I don't have root authority, but I have the password of the second user. what should I do? I have tried shell "su - " can switch current user, can this command help me in my C++ code? Don't laugh at me if my question is very stupid, I'm a true freshman on linux. :) Thanks!

• Processing a method after the view has loaded..

  - by Susanth

  Hi ! I have implemented a subview which is supposed to load immediately when I click a button in the parent view. After loading the subview(which is basically holding an activityindicator), the program is supposed to process a method(which gets data from a server, so takes time) in it. However, I am unable to do it. What happens now is, when I click the button on the parent view, it processes the method first and only after that does the subview load on screen. Why is this so? Is there any specific functions I could use to make my method load only after the view has loaded?

• How to efficiently render different things at different times in a game?

  - by Baqjohanson

  Sorry for the ambiguous title. What I am wondering is what is an efficient way to alternate rendering between lets say a main menu, options menu, and "in the game." The only two ways I've come up with so far are to have 1 render function, with code for each part (menu, ...) and a variable to control what gets drawn, or to have multiple render functions, and use a function pointer to point to the appropriate one, and then just call the function pointer. I always wonder how more professional games do it.

• Android HTTP get methods

  - by Nick

  I have written a number of applications for blackberry and am just starting in Android. It seems to me that android has a lot more built in functions. I am starting by recreating some of my BB apps on Android and on one I take a few xml sites and parse them out. On blackberry I implemented this by creating a class that extended a thread. I would construct a new instance of this class with the parameters of my http request and it would call a function back in my main class, sending it the results. I am tempted to reuse my code, but am curious if android has something better built in. I have been looking at the handler class as well as possible using a service. Bascially, I would like to start a new thread that will return a document of a specific url. Thanks!

• How do I remove line references in generate output in doxygen?

  - by MeThinks

  I want to remove lines look as follows but I still want to return source code browsing Definition at line 377 of file xxx.h. I have tried the following two in the doxygen config file but these just remove cross references on types # If the REFERENCES_RELATION tag is set to YES # then for each documented function all documented entities # called/used by that function will be listed. REFERENCES_RELATION = NO # If the REFERENCES_LINK_SOURCE tag is set to YES (the default) # and SOURCE_BROWSER tag is set to YES, then the hyperlinks from # functions in REFERENCES_RELATION and REFERENCED_BY_RELATION lists will # link to the source code. Otherwise they will link to the documentation. REFERENCES_LINK_SOURCE = NO update: I've just trying setting the following and seems to do the jobs but waiting to confirm if this is the correct way of achieving what I want SOURCE_BROWSER = NO

• Getting the fractional part of a float without using modf()

  - by knight666

  Hi, I'm developing for a platform without a math library, so I need to build my own tools. My current way of getting the fraction is to convert the float to fixed point (multiply with (float)0xFFFF, cast to int), get only the lower part (mask with 0xFFFF) and convert it back to a float again. However, the imprecision is killing me. I'm using my Frac() and InvFrac() functions to draw an anti-aliased line. Using modf I get a perfectly smooth line. With my own method pixels start jumping around due to precision loss. This is my code: const float fp_amount = (float)(0xFFFF); const float fp_amount_inv = 1.f / fp_amount; inline float Frac(float a_X) { return ((int)(a_X * fp_amount) & 0xFFFF) * fp_amount_inv; } inline float Frac(float a_X) { return (0xFFFF - (int)(a_X * fp_amount) & 0xFFFF) * fp_amount_inv; } Thanks in advance!
